Hereís a book story for you. Cartoon-lovers will recognize it as borrowed from Brother Brat, a 1944 Looney Tunes where Porky the Pig is dragooned to babysit for Rosie the Riveter while she goes to weld planes to help "the United Nations fight Schickelgruber and Tojo." Before she leaves, Rosie thrusts into Porkyís hands a thick copy of a book called Child Psychology, saying, "Here, this might help you."
